      EXALOS releases NEW Ultrabroadband Superluminescent Light Emitting Diodes for Medical Imaging and Sensor applications

      EXALOS has expanded its portfolio of Superluminescent Light Emitting Diodes (SLEDs) by introducing our new near-IR Combi-SLED modules where multiple SLED devices are spectrally combined to provide an ultra-broadband spectrum. The light output of the SLEDs are collimated using micro-optical collimation lenses, spectrally combined and colinearly aligned through free-space dielectric edge filters and focused into a single-mode fiber. The Combi-SLEDs are especially suited for medical imaging applications such as ultra-high-resolution Optical Coherence Tomography (UHR-OCT) and Fiber Optic Sensor applications thanks to their high output power. large spectral bandwidth and short coherence length. The first product release of such a Combi-SLED ...

    2. EXALOS Introduces RGB Modules for Augmented Reality and Head-up Display Applications

      EXALOS Introduces RGB Modules for Augmented Reality and Head-up Display Applications

      EXALOS, the world’s leading developer of visible Superluminescent Light Emitting Diodes (SLEDs), has expanded its product porfolio with the introduction of a compact RGB SLED module that will enable the advancement of micro-display architectures for augmented reality (AR) and head-up displays (HUDs). The RGB module constitutes three SLED chips housed in a 14-pin butterfly package (20.8 mm x 1.7 mm) with a total output power of about 30 mW (~ 10 mW/color), which corresponds to a total luminous flux of 5 lm. The individual chips (635 nm (R), 510 nm (G), and 450 nm (B)) are each ...

      EXALOS releases NEW High-Power 840nm Superluminescent Light Emitting Diodes (SLEDs) for Medical Imaging and Sensor applications:

      EXALOS releases NEW High-Power 840nm Superluminescent Light Emitting Diodes (SLEDs) for Medical Imaging and Sensor applications: For SD-OCT applications, higher output power from the SLED allow for more asymmetric splitting ratios in the interferometer and therefore in lower losses for the received OCT signal, enabling higher acquisition speeds or higher sensitivity. Higher-power SLEDs also help realizing surgical ophthalmic systems or multi-modal imaging systems where the OCT path is shared and therefore experiences higher losses.
